M31 SL
The rockSteel Screwlock has a large gate opening and precise handling characteristics due to CNC machined surfaces. Professionals appreciate the smooth spinning screw-sleeve and the smooth keylock surface that won't snag your rope.
The rockSteel offers a surprising strength-to-weight ratio in a carabiner of its capacity. Most steel carabiners are made from 1/2 diameter steel. We use a lighter, 7/16” diameter steel that is heat treated for added strength.
Like our aluminum carabiners, the rockSteel frames are CNC machined for precise fittings and exact tolerances. The result is a carabiner with a feel like no other steel carabiner in the world.
The rockSteel Screw-lock has been UL tested to NFPA "G" standards.
